无法在 r 工作室中加载 package kknn

Question

looks like the package has been successfully installed, however, the below message keeps appearing:

Error: package or namespace load failed for 'kknn' in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]): there is no package called 'lattice'

The kknn package was successfully installed before today. But I can't knit the document to pdf, so I installed a package called latexpdf . After that, the whole RStudio just doesn't function well. I don't know what happened... tried to re-install but doesn't help.

Does anyone know what should I do with this? thank you!

Answer 1

Thanks for the modification!

I installed Lattice package and the problem solved...what a silly question...
